BATTERY SYSTEM INCLUDING IMPROVED ELECTRICAL CONNECTING ELEMENTS

A battery system includes a housing and a plurality of battery cells accommodated in the housing, with each of the battery cells including cell terminals. The cell terminals of neighboring battery cells are electrically interconnected via electrical connecting elements. Each electrical connecting element includes a first layer contacting neighboring cell terminals and a second layer disposed on top of the first layer. The melting point of the first layer is greater than a melting point of the second layer.
